Any comments...

As I was first looking at them I was thinking it might be a good way to reduce weight but the closer I looked, the peaks were so high the the added wood from them looks like more than the holes take out. All in all it looks like more wood not less to me. I say gimmick.

In the 80's this was a common thing to do on racebikes. Anything was done to reduce weight. Brakebrackets, clutchdiscs, frameplates, you name it. In the last decades computer aided design (weight/strenght) and engines with almost unlimited power make this drilling practice obsolete. On a soundboard a very high brace has no major visual consequence. But on a racebike you do not want an ugggely bracket that is thin, but very large. The math wants a part and the eye/ear too. A burdon they are, those compromises.
